PHILADELPHIA (CBS) - When 18-year-old Maxwell Koder stepped up for his country, his brothers Brandon and Michael weren’t far behind.

“It’s all we’ve ever known for the past 18 years−just being by each others side and helping each other out,” said Michael Koder.

So it’s no surprise they were inspired by Max’s interest in the military and decided to give it a try themselves. Now, the triplets are enlisted in the Air Force, after taking ROTC and graduating from North Penn High School last month.

“Very special, very special,” said Air Force Staff Sergeant Jessica Kosisky.

Having enlisted the three, Staff Sergeant Jessica Kosisky told us each brother will learn to fly, fight and win, but all in different ways. Max will specialize in security forces, while Brandon handles munitions and Michael focuses on vehicle maintenance.

“I’m like a proud Air Force mom. I get to see them as normal civilians and come back in a year in uniform… and I’ll be very proud,” she said.

With their enlistment contracts signed, the boys will head off to basic training in August. So I had to ask who would be tougher… their drill sergeant or dad?

“I’d probably go with Dad. Yeah I’m going to have to go with them…Dad,” said father Michael Koder.

He doesn’t have military experience, but he runs a tight ship. That is, until his boys take flight in a few weeks.

“It’s going be tough, never believed in empty nest syndrome. I’m starting to feel that now,” he said. “But again, they’re going to be happy and have opportunities of a lifetime like I never did.”

Bringing honor to their country and their family, three times over.
